Sammamish, WA Animal Ordinances: Pet Limits (2026)

Sammamish does not impose a simple numeric pet limit per household; instead it adopts King County Code Title 11 (SMC 11.05), which uses a hobby kennel/cattery licensing scheme. Under KCC 11.01.210 and 11.01.200, a 'hobby kennel' is a noncommercial kennel where four or more non-juvenile dogs are kept, and a 'hobby cattery' covers four or more non-juvenile cats. Operating one requires a hobby kennel or hobby cattery license (KCC 11.04.060), and the maximum number of animals scales with lot size: lots under 20,000 square feet are limited to about 3 animals; lots of 20,000 to 35,000 square feet up to 5; and larger lots gain two more pets per acre beyond 35,000 square feet, up to a maximum of 20, with no more than 3 of the total left unaltered. Juveniles (under six months) are generally not counted toward the limit. The hobby kennel/cattery license also carries care conditions such as fencing of run areas and limits on litters per year. Households keeping three or fewer dogs and three or fewer cats typically stay below the license threshold. All non-juvenile pets must be spayed or neutered unless the owner holds an unaltered-pet license.
